Write junit for the following code: package com.talentica.service; import com.talentica.dto.NotificationDto; import com.talentica.enums.NotificationFilter; import com.talentica.mapper.NotificationMapper; import com.talentica.model.Notification; import com.talentica.repository.NotificationRepository; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.data.domain.Page; import org.springframework.data.domain.PageRequest; import org.springframework.data.domain.Pageable; import org.springframework.data.domain.Sort; import org.springframework.stereotype.Service; @Service public class NotificationService { @Autowired private NotificationRepository notificationRepository; @Autowired private NotificationMapper notificationMapper; public Page getNotificationsByUser(Long userId, NotificationFilter filter, int page, int size) { Pageable pageable = PageRequest.of(page, size, Sort.by("receivedAt").descending()); Page notifications; switch (filter) { case ALL: notifications = notificationRepository.findByUserUserId(userId, pageable); break; case UNREAD: notifications = notificationRepository.findByUserUserIdAndReadAtIsNull(userId, pageable); break; case READ: notifications = notificationRepository.findByUserUserIdAndReadAtIsNotNull(userId, pageable); break; default: throw new IllegalArgumentException("Invalid filter value: " + filter); } return notifications.map(notificationMapper::notificationToNotificationDto); } }

Here is a JUnit test for the NotificationService class:

    private NotificationRepository notificationRepository;

    private final Long userId = 123L;

    @BeforeEach
    void setUp() {

        notificationService = new NotificationService();
        notificationService.notificationRepository = notificationRepository;

    }

    @Test
    void testGetNotificationsByUser() {
        int page = 0;
        int size = 10;
        PageRequest pageRequest = PageRequest.of(page, size, Sort.by("receivedAt").descending());

        List<Notification> notificationList = new ArrayList<>();

        notification1.setId(1L);
        notification1.setReadAt(null);
        notificationList.add(notification1);
        Notification notification2 = new Notification();
        notification2.setId(2L);
        notification2.setReadAt(null);

        NotificationDto notificationDto2 = new NotificationDto();
        notificationDto2.setId(2L);
        NotificationDto notificationDto3 = new NotificationDto();
        notificationDto3.setId(3L);

        when(notificationMapper.notificationToNotificationDto(notification1)).thenReturn(notificationDto1);
        when(notificationMapper.notificationToNotificationDto(notification2)).thenReturn(notificationDto2);
        when(notificationMapper.notificationToNotificationDto(notification3)).thenReturn(notificationDto3);

        Page<NotificationDto> notifications = notificationService.getNotificationsByUser(userId, NotificationFilter.UNREAD, page, size);

        verify(notificationRepository, times(1)).findByUserUserIdAndReadAtIsNull(userId, pageRequest);
        verify(notificationMapper, times(1)).notificationToNotificationDto(notification1);
        verify(notificationMapper, times(1)).notificationToNotificationDto(notification2);
        verify(notificationMapper, times(1)).notificationToNotificationDto(notification3);

        assertEquals(3, notifications.getTotalElements());
        assertEquals(1L, notifications.getContent().get(0).getId());
        assertEquals(2L, notifications.getContent().get(1).getId());
        assertEquals(3L, notifications.getContent().get(2).getId());
    }
}

In this test, we are testing the getNotificationsByUser() method of the NotificationService class. We are using Mockito to mock the dependencies of the NotificationService class, which are NotificationRepository and NotificationMapper. We are then setting these mocks in the notificationService object using reflection.

We are then creating a list of `Notification

These test cases cover the three possible values of the `NotificationFilter` enum as well as an invalid value. They also test that the correct repository methods are called and that the mapper is correctly converting `Notification` objects to `NotificationDto` objects.

Write junit for the following code: public class WeightUtil { private WeightUtil() { } public static double getWeightOnMars(double value) { return (value / 9.81) * 3.711; } }

Here's an example JUnit test case for the WeightUtil class:

javaCopy code
import org.junit.jupiter.api.Test;
import static org.junit.jupiter.api.Assertions.*;

public class WeightUtilTest {

  @Test
  void testGetWeightOnMars() {
    double value = 68.0;
    double expectedWeight = (value / 9.81) * 3.711;
    double actualWeight = WeightUtil.getWeightOnMars(value);
    assertEquals(expectedWeight, actualWeight, 0.01);
  }
}

This test case checks that the getWeightOnMars method correctly calculates the weight of an object on Mars. It does this by providing a value of 68 kg and comparing the expected weight with the actual weight calculated by the method. The assertEquals method is used to check that the two values are equal, with a delta of 0.01 to account for potential rounding errors.
